Brand: Puritan's Pride · Form: SUPPLEMENT FORM, OTHER [E0172] On Market
Our assessment
The evidence shows that Puritan's Pride Calcium 600 + Vitamin D3 is a straightforward supplement providing two nutrients that work together. Our assessment is that it can be a useful tool for supporting bone health, but you need to be aware of specific risks and medication interactions before taking it [NIH ODS].
How it works
Think of this supplement as providing a bone-building team. The calcium supports bone density and mineral deposition, which is the process of keeping your skeleton strong. The vitamin D3 helps your body absorb that calcium efficiently. This combination is especially important for maintaining neuromuscular function, as calcium is essential for muscle relaxation and nerve signaling [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements, but specific side effect counts for this product are not available. You should be aware that high calcium intakes from supplements might increase the risk of heart disease and prostate cancer. Very high levels of calcium in your blood and urine can lead to poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data].
Our recommendation
Before starting, check your current calcium intake from food and other supplements. You must take this supplement at least two hours apart from medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin, as calcium can reduce their absorption [NIH ODS]. Start with one tablet daily with food, and do not exceed the recommended dose without a healthcare provider's guidance.
